As TB says, what could possibly go wrong? I sure hope that works, but I'd bet against it if I were a betting man. And in the interest of this and future missions I hope they pull it off.

Watching that, something as simple as the load being a bit off center would cause the thrusters on the opposite side to over-worked and run out of fuel. I know they've thought of that, and most everything else, it just seems like a fragile system to me.

If I were a betting man I'd bet, too, that half of the designers of that descent and landing system have dogs which won't come when they call them. I don't know fer sure how that relates, but it does.
